Abstract

The CCA-adding enzyme [ATP(CTP): tRNA nucleotidyltransferase (EC. 2.7.7.25)] catalyses the addition of the conserved CCA sequence to the 3'-terminus of tRNAs. All CCA-adding enzymes are classified into the nucleotidyltransferase superfamily. In the absence of ATP, the Escherichia coli CCA-adding enzyme displays anomalous poly(C) polymerase activity.
